I'm working on a post entitled "Does tonight's biggest Guam earthquake in three years and some other things signal November 15-16 is a "Day of Burning"?"

--and just saw the EMSC bulletin about these two quakes on the Eastern coast of South Korea:

Mainshock 12:30 a.m. EST 11/15/2017
Magnitude 5.4

Aftershock 12:33 a.m. EST 11/15/2017
Magnitude 3.6

There is no report yet about it at Korea Times online but soon will be, I see these interesting eadlines there:

Today's quake in South Korea is the strongest since September 12, 2016, here's my comments of November 6 about it:

: 420 days ago occurred the biggest earthquake in South Korea's
: history. Magnitude 5.8 or 5.4, it happened at 6:33 a.m. CDT
: Monday September 12, 2016 and was preceded by a magnitude
: 4.9 foreshock at 5:44 a.m.

: Oddly, a rare South Korean quake happened at 6:33 a.m. CDT
: July 5, 2016...and then a week after the September 12
: mainshock at 6:33 a.m. CDT, a magnitude 4.6 aftershock
: struck at 6:33 a.m. CDT Monday September 19.
